Having worked in county fire/medical dispatch I feel as though the 911 tapes and other communications that are recorded in dispatch are a matter of public record. Making these tapes public is a way of assuring that there is a level of transparency in the dispatching process, a way for the public to know and understand how their crises are being handled on the dispatching side of it. Also, because of HIPPA regulations any names and addresses are deleted before being made public, so unless the caller is wildly famous, generally there is a level of privacy or anonymity there.
